FIELD: agricultural engineering.;SUBSTANCE: invention can be used for open delivery drilling on soils suffering from wind erosion. Proposed opener has hoe, post and soil separator-distributor. Separator-distributor in rear part of hoe opener is made in form of rods. Extreme rods are arranged in longitudinal vertical plane, being orientated at an angle upwards. Free ends of pair of central rods are brought to axis of symmetry of seeding strip at level of hoe blade. Free ends of other rods, in combination with ends of extreme and central rods, form concave trajectory cross-vertical plane. Soil getting onto separator-distributor from opener hoe gets screened through grill formed by rods and moving along rods uniformly covers furrow in width. Fine particles of soil cover seeds, and large particles lie on field surface preventing erosion processes.;EFFECT: improved quality of seed covering, prevention of wind erosion of soil.;2 dwg
